Performance Analysis of the Steam Turbine Cycle Combined with the Heat Pump

抄録

The performance of the steam turbine cycle combined with the heat pump is analyzed from the standpoint of both the 1st law and 2nd law of thermodynamics. this cycle is useful in order to reduce the thermal pollution locally caused by the waste heat from the steam condenser and to raise the total energy efficiency. The following factors are considered here to analyze the performance of this cycle ; the internal efficiency of the steam turbine, the pressure of the steam condenser in the steam cycle, the kind of thermal media (NH₃, Rll), the condensing temperature, the evaporating temperature, the outlet, temperature of the cooling water from the evaporator and the internal efficiency of the compressor in the heat pump cycle.
